--- Introduction: Chronic obstructive pulmonary disease (COPD) is a complex multicomponent heterogeneous disease characterized by the presence of poorly reversible limitation of airflow, whose clinical, functional and radiological presentation varies greatly from one patient to another. Nowadays we use the concept of clinical phenotypes in COPD to differentiate individuals with this disease, it is related to relevant issues, such as symptoms, exacerbations, response to treatment, disease progression or death. Objectives: Objectives: To determine the dominant clinical phenotype in patients with COPD of Daniel Alcides Carrión Hospital during the month of January 2016. Design: A crosssectional descriptive study. Setting: The pulmonology medical office of Daniel Alcides Carrion Hospital. Participants: 58 patients diagnosed with COPD, with a sample of 51 patients. Interventions: All information was obtained from medical records. To classify phenotypes were used GesEPOC guidelines. Main outcome measures: clinical phenotypes in COPD. Results: Of 51 patients, 10 are distributed in the exacerbator phenotype (20%), 13 patients (25.5%) in mixed phenotype COPD-asthma, in the phenotype emphysemahyperinflation a total of 12 patients were enrolled (24% ) and chronic bronchitis phenotype in 16 patients (31%) with main symptom cough associated with expectoration. Conclusions: Four types of phenotype were observed in patients registered; being the dominant type chronic bronchitis phenotype. There was an increase in the male population in the exacerbator phenotype and female population in chronic bronchitis phenotype Keywords: COPD, phenotype, HNDAC
